Single coil noise reduction procedure?

search better!

A single coil will always have some hum and buzz, no matter shielding you do.

superior shielding with copper foil, well overlapped and soldered. the conductive paint they use nowadays in the guitar cavaties doesnt cut it. johnny a

 

Staindbass,
is it better than copper based shielding?
what about aluminium foil?
Any hints where to buy?
thanks
Robert

 

Aluminum foil is a poor conductor. It's best to use copper.

 

Stew-Mac is one source for Copper Foil Shielding Tape.

 

I can't get over how quiet my Jay Turser JTB-401 is. At the GTG I was wowing everyone who paid attention. Yes, there is the signature 60 cycle hum but it is so quiet even at loud amp volume in my basement full of compact fluorescent bulbs.

 

Aluminum is a good conductor, actually. It does not conduct as well as copper, but at least one TBer with a degree in physics says that doesn't matter in this context: Click here to see the previous thread.

hi robert , you mean the paint? no it doesnt work as good as the copper. but its easier to apply. if you are going to do it, figure out the shape of the pieces using paper to fit in the cavity. make sure to leave overlap to solder. once you have it nice, take the paper pieces out and trace them on the copper . dont forget the the control cavity cover if you have one. johnny a

 

you could try the electro harmonix humdebugger pedal.
i bought one recently for my dark starred bass and it does wonders. as i understand it, it identifies your hum and creates the opposite/negative frequencies so it cancels out. it has a normal and strong setting. the strong setting is fairly useless as it effects the actual tone of your bass far too much, but the normal setting gets rid of a lot of hum, at minor tone expense(which is worth it in my opinion).

 

Aluminium foil is a pain to solder, while copper is easy but costs more. I use aluminium foil for the back of pickguards.

An aside but related question: When you use shielding, is it really that important to not leave a single crack where the hum can get in/out? Or does close count? Just how meticulous do I have to be?

 

Bumping this thread. A few unanswered questions...
